Grafana
Grafana is a popular tool that helps companies visualize and understand their data through charts, graphs, and dashboards. Think of it like creating a customized control panel that shows important business information in real-time. It's particularly useful for monitoring how well computer systems are performing, tracking business metrics, and spotting problems before they become serious. Many companies use Grafana because it can connect to various data sources and present information in an easy-to-understand way, similar to how Microsoft Excel creates charts but in a more automated and real-time manner.
